Exception invoking fish shell from Powershell

First reproduce the reported fish command from PowerShell 7.5 on Darwin and trace the stack through RecomputeInitialCoords, ReallyRender, and ForceRender. Done means the command completes without PSReadLine raising the reported InvalidOperationException.

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues, especially the pinned issues.
